Bimodal changes of T1 relaxation time. Panel a short-axis T1 maps in a patient with inferior ischaemic injury (black arrow) acquired at three time points post STEMI presentation. The magnitude of change in native T1 value within the area at risk (AAR) (contoured in black) is illustrated against a colour scale map. Panel b T1 relaxation time showed significant attenuation of oedematous reaction in the injured myocardium after 24 h and returns to previous level at 6 days (blue lines representing mean +/− 2 standard error). Changes within remote myocardium over time are illustrated in black lines (mean +/− 2 standard error). Panel c excluding central area with low T1 values (T1-core), T1 relaxation time was compared serially. The deferred wave of oedematous reaction was more prominent with significant difference between 24 h and 6 days (blue lines representing mean +/− 2 standard error)
